Reliable and economical, mechanical demand operated drain valves do not waste any valuable compressed air. They detect the presence of liquid and only operate when filled to a pre-determined level. Upon actuation, they discharge only liquid and close before any compressed air can be exhausted. Fully automatic, mechanical demand operated drains do not require electricity to operate.
